Daly Rules Approach
A set of three operational rules that define the conditions of ecological austainability, developed by and named after former Senior Economist for the World Bank Herman E. Daly. According to the Advisory Committee on Water Information, the rules are as follows:
- renewable resources such as fish, soil, and groundwater must be used no faster than the rate at which they regenerate
- non-renewable resources such as minerals and Fossil Fuels must be used no faster than renewable substitutes for them can be put into place
- pollution and waste must be emitted no faster than natural systems can absorb them, recycle them, or render them harmless.
